How to Archive To Glacier


February 27th, 2015

Lots of people have emailed me asking for a way to put their stuff on Glacier and then delete it from their hard drives, because they’re running out of disk space. I used to think that disk space was becoming so plentiful that this would never be a problem, but the disk-space growth graph started over with the advent of SSDs, so I guess we’re not there yet!

Arq is our backup app that reliably backs up your files to your own Amazon Glacier account. It has always expected the files to remain on  your disk. But now we’ve changed that! You can pick a folder and mark it as an archive.

Add a folder to Arq, and choose “Glacier storage class” when prompted. (This is assuming you’re using AWS as your backup destination). When it’s been backed up, select it and click the “Detach” button:

Archive Folder to Glacier

The icon for the folder will change to a box, and the backups of that folder will stay in your AWS account, but Arq won’t try to back it up anymore. Now you can delete your files from your disk, but restore them from Glacier if you ever need them!

To “re-attach” the folder so that Arq starts backing up again, select it and click the “Attach” button (where the “Detach” button used to be):

Attach to Archived Folder

By the way, you can do this no matter what destination type you’re using, whether it’s Amazon Glacier, S3, Dropbox, Google Drive or SFTP.

As always, if you have any questions please email and we’ll help you out.

Arq Backs Up to Your Dropbox Account


February 23rd, 2015

Arq 4.8 is now available, and it includes support for backing up to your own Dropbox account!

If you already have a Dropbox with 1TB of space, now you can use that space for your Arq backups. The Arq backups go into the folder /Apps/Arq in your Dropbox account.

As always, all your data are encrypted before they leave your computer, using a password that only you know, so your files are safe and secure; and the backups are in an account that you control. All the other features of Arq apply as well, including versioned backups, full OS X metadata backups, email notifications, and the ability to restrict which wifi networks Arq uses.

You can even combine Dropbox with other destinations in Arq. For instance, you can back up all your files to both Dropbox and your SFTP server. Or back up some files to your Dropbox account, some files to your Google Drive account, some files to your Amazon account, and some files to your SFTP server. It’s entirely up to you. For example, I’m backing up a variety of folders to 4 different destinations:

How to Recover Your Things Database with Arq


February 14th, 2015

The other day Wendy emailed me because Things crashed and she lost a lot of work, and she couldn’t figure out how to get back her data using Arq.

We traded a few emails over the next few hours, but it quickly became clear to me that she wasn’t wasn’t comfortable digging into her Library folder and move files around. So we jumped on Skype and did it together. She shared her screen with me so I could follow along with what she was doing.

The support person for the Things app had emailed her a web page with the location of the Things database, and we actually found some backups that the Things app had made by itself, but the newest one was a day old and the work she had lost had been added that morning.

So Wendy and I found a more recent Things database in her Arq backups and restored it.  Here’s how to do that:

  1. Quit the Things app.
  2. Click the Finder on the Dock.
  3. Click “Go to Folder” from the Finder’s “Go” menu, enter the path ~/Library/Containers/com.culturedcode.things/Data/Library/Application Support/Cultured Code/Things/ and click “Go”.
  4. Click the “ThingsLibrary.db” file once to highlight it.
  5. Click it a second time to rename it. Change the name to “ThingsLibrary.db_old”.
  6. Open Arq.
  7. Click the triangle next to your home folder.
  8. Select the most recent backup record (or whichever backup you want to use).
  9. Click the triangles to drill down to the same folder as mentioned in Step 3: Library/Containers/com.culturedcode.things/Data/Library/Application Support/Cultured Code/Things/
  10. Select the “ThingsLibrary.db” file and click the “Restore” button:

  11. Wait until Arq finishes restoring the file.
  12. Launch the Things app. You’ll see your Things data as of the backup date that you chose in step 8.
  13. To look at your Things database as of a different point in time, repeat the above steps, choosing a different backup record in step 8.

If you want to go back to the Things database you had before, quit Things, go back to the Finder, delete the “ThingsLibrary.db” file, and rename the “ThingsLibrary.db_old” file back to “ThingsLibrary.db”.

If you run into trouble with an app and you’re not sure how to restore the app’s data from a backup, send me email at and we’ll figure it out!
